2 the container (i. e., under the hatch I1) are rigidly secured to and supported by the beams 42 43,-said beams also serving as the lower chords of the sides 32. The non-rigid sections of the bottom 33 are at the ends of the container I8 and comprise inverted channel shaped slats 44 shorter than the clear distance between the beams 42 and 43. As shown in Fig. 6, the slats 44 are supported above and secured to the drip pan I9 by the element 45 having portions 46' adjacent the slats 44 alternating with portions 41 adjacent the drip pan I9.

.lease of the latch container bottom to thel force exerted by The drip pan is secured to a plurality of arms 55 which are pivoted at fulcrums 56. The fulcrum 56 is shown in Figs. 1-3 secured to the beams 42 of the' container I8., Although this construction is to be preferred, it is understood that any arrangementin which the fulcrum is supported by the car structure is'included within the scope of this invention. For example, Fig. 'I shows the fulcrum 56 mounted on a bracket E51 supported by the wall structure 30 of the car.

A plurality of springs 65 are arranged so that the force exerted by said springs tends to rotate the arms 55 in a counter-cloc the fulcrums 56. The upper end of each spring 65 bears against the horizontal portion 66 of fthe bracket 61, thevertical portion 68 of said bracket 61 being secured to the side wall structure 30. A rod 69 having a spring seat 10 attached to the lower end' thereof is pivotally connected to the arm 55 by the pin` 1I; thus, any downward movement of the drip pan I9, the spring 65 is compressed between the horizontal portion 66 and the seat1Il. erted by the spring 65 tends to return the partition I9 to its normal horizontal position.

A plurality of supports 15 extend' between the containers I8 and have straps y16 swingably suspended therefrom. The upright walls 20 are secured to the straps and serve the double purpose of forming a duct 2| for upward movement of'air' and of supporting the drip pan I9. A latchlike mechanism 11 fastened to the `wall 20 holds the drip pan I9 in a horizontal position but re- 11 allows the drip pan and swing downwardly against the spring.

Fig. 8 shows a modified for the partial retention of`brine. The bottom weight of drip Aupon the I8 is imperforate and has an flange 86 entirely surroundbottom to serve as'a stiffener and to the top of the flange 86. The the container I8 .comprises 81. Iillhe bottom 85 is supported drip pan I9 by the elements 45 and associated with the arm 55 ously'descrlbed. The drawings show the arm 55 hinged to the bracket` 88 which is supported from the side -wall structure of the car. The arm 55 may `also .be hinged to the container I8 or any 85 of the container retain brine tp upper part of' foraminous walls 'other part of the car structure and be within 'the scope of the invention.

The danse 86 retains a considerable amount of brine to insure a low temperature and the foraminous upper walls 81 allow the air to contact the ice and also facilitate Ventilating the car.

When it is desired to remove the ice fromthe container I8 the latch 11 is released and the drip pan I9, to which the container bottom' 93 is secured, is allowed to swing downwardly. The pan I9, container bottom 33, and ice resting on said bottom is partly resisted by the force ofthe spring 65, thus making the work when tions thereof,

' e direction about The-force thus exhatch'in combination with a construction .designed and spring 65 as previlthe rest of the container, said the ice has been removed the spring 65 partly or wholly returns the drip pan I9 and container bottom 33 to their closed positions.

'I'he drawings show the entire drip pan I9 hinged and the end portions 44 of the container bottom 33 separate from the container and secured to the drip pan. It is understood that other arrangements, such as supporting the entire con- .tainer bottom upon the drip pan or hinging only the part of the drip pan supporting the container bottom, are only are included within the scope tion.

The accompanying drawings ferredform of the invention, though it is to be understood that the invention is not limited to the exact details of constructionL shown and described, as it is obvious that various modificawithin the scope ofthe claims, will occur to persons skilled in the art.

I claim:
